Among dental restorations, implants are the closest prosthetic we have to real teeth. They not only replace the visible crown, but the titanium post imbedded in the jawbone adequately substitutes for the tooth root. Because of their unique design, implants are not only life-like, they’re highly durable and could potentially last for decades.
But while their success rate is remarkably high (more than 95% exceed the ten-year mark), they can fail. Ironically, one possible cause for implant failure is periodontal (gum) disease. Although an implant’s materials are themselves impervious to disease, the tissues and underlying bone that support the implant aren’t. If these natural tissues become infected, the secure hold the implant has can weaken and fail.
A gum infection usually begins with dental plaque, a thin biofilm of bacteria and food particles that builds up on tooth surfaces. Certain strains of bacteria within plaque can infect the gums. One particular form of the disease known as peri-implantitis starts as an initial infection and ensuing inflammation of gum tissues around an implant. The disease can quickly spread down to the bone and destroy the integration between the bone and the implant that helps keep the implant in place.
That’s why it’s important for you to keep the implant and the tissues around it clean of plaque, just as you would the rest of your natural teeth. This requires daily brushing and flossing around the implant and other teeth, and visiting your dentist regularly for more thorough dental cleanings.
You should also be alert to any signs of disease, especially around implants: gum redness, swelling, bleeding or pus formation. Because of the rapidity with which peri-implantitis can spread, you should see your dentist as soon as possible if you notice any of these signs.
Preventing gum disease, and treating it promptly if it occurs, is a key part of implant longevity. Preserving your overall dental health will help make sure your implant doesn’t become a loss statistic.
Years ago, disease or trauma robbed you of one of your teeth. At the time you might have opted for an affordable solution, like a partial denture. But now you'd like to restore that missing tooth with a dental implant, the most life-like tooth replacement available.
That's a great decision. But there may be a hiccup along the way to your new implant: the state of the underlying jawbone. Implants need a certain amount of bone for proper placement. If not enough is present, that may cause an interruption in your plans—and that could be a real possibility if your tooth has been missing for some time.
That's because, like other living tissues, bone has a growth cycle: Old bone cells die and dissolve, while new cells form to take their place. In the jaw, the force produced by teeth during chewing helps to keep this growth process in the bone functioning at a healthy pace.
When a tooth goes missing, though, so does this chewing stimulation. A lack of stimulation can slow the growth rate for that part of the bone and its volume can diminish over time. It's possible for a quarter of the bone volume to be lost within the first year after losing a tooth.
If you've experienced that level of bone loss, we may not be able to place an implant—yet. You might still have a few options. For one, we could attempt to regenerate some of the bone through grafting. Bone material grafted into the affected area can serve as a scaffold for new bone cells to form and adhere. Over time, this could result in a sufficient amount of regenerated bone to support a dental implant.
Another possibility might be to install a smaller diameter implant like those used to support removable dentures. Because they're smaller they require less bone than standard-sized implants. They're not for every situation, though, and are best suited for situations where aesthetics isn't a priority.
To know what your options are regarding an implant-based restoration, you'll need to undergo a thorough evaluation of your oral health, including supporting bone. Depending on your situation, you may still be able to renew your smile with this premier tooth replacement option.

To keep a healthy smile, brushing and flossing your teeth every day should be at the top of your to-do list, along with regular dental visits. Dental visits are usually scheduled every six months when your dental professional will remove any built-up plaque and tartar (hardened plaque deposits) missed during everyday hygiene.
If you've experienced periodontal (gum) disease, however, these dental visits may become even more important toward preventing a re-infection. For one thing, your dentist may want to see you more frequently.
Gum disease is caused by bacteria living in dental plaque, which first infect the superficial layers of gum tissue. Even though the body initiates an inflammatory response to fight it, the infection continues to grow as long as there is plaque present to fuel it. The problem isn't just plaque on the visible tooth surface—hidden plaque beneath the gum line can create deep pockets of infection that can be difficult to treat.
To stop the infection, dentists must manually remove plaque through procedures known as scaling and root planing. Any and all plaque and tartar deposits must be removed, even those deep around the roots, to arrest the infection. This often requires several treatment sessions and sometimes gum surgery to access areas below the gum line.
These types of treatments, especially in the disease's early stages, have a good chance of restoring health to your gums. But because of the high possibility of reinfection, your dentist will need to step up your regular dental maintenance from now on. This could mean visits as frequent as every few weeks, depending on your particular case of gum disease and your dentist's recommendation.
Your dental visits after gum disease may also become more involved than before. Your dentist will now monitor you closely for any signs of reinfection and at the first sign initiate a new round of treatment. You may also need surgical procedures to make some areas around your teeth more accessible for future cleaning and maintenance.
Periodontal maintenance after gum disease helps ensure another infection doesn't rise up to undermine your progress. To paraphrase a well-known quote, eternal vigilance is the price of continuing good dental health.
